278 SOUTH AFRICAIS* FERN NOTES. 



actions of the Eoyal Society of South Africa," vol. v., part 4, 

 May, 1916, in which is included 126 species and thirteen varieties 

 of Pteridophyta, from which, however, a few have toi be altered 

 as follows : — 



DavalJia conciiina, Sclirad., and D. tJiecifcm, H.B.K., are 



synonymous, and are now included in Asplcniurn 



iheciferu7n, H.B.K. 

 Ancimin tomentosa, Sw. ; Teague's No. 60 cited belongs to 



A. antliriscifolia, Schrad., and there is no other record of 



.4. tomentosa for S. Rhodesia. 

 Aspidiiini cnnmi folium, Poir, is the South African form of 



Polystichnm aculcatum (Linn.), Schott, and represents 



that species in Eyles' list. 

 Cyathea manniana, Hoek, and C. thomfiotti, Baker, may be 



good species, and may be present, but Swynnerton's 



6030 and 817, as sent to me by him, are both C. dregci, 



Kunze. 

 PoJypodium ohtu.silolun)i , Desv., is a. condition of Dryoptcris 



bergiana, O. Ktze. 

 This reduces Ejles' list to 121 species and 18 varieties. 



In "Ferns of So^uth Africa," 1st edition (1892), 24 

 species were mentioned as Eliodesian ; in the 2nd edition (1915) 

 126 species, and now I have records of 140 species besides 20 

 varieties, a few of which, however, have rather indefinite locality 

 records, such as " Zambesi highlands " or " Zambesia." 



Eyles' list followed the nomenclature of my first edition, 

 which was based on Baker's " Synopsis Filicum." Unfortunately 

 the researches of C. Christenson, 0. Kuntze, Prince Bonaparte 

 and O'thers had so' completely revolutionised the generic nomen- 

 clature that wholesale readjustment became necessary in my 

 second edition, which follows Christenson 's " Index Filicum " 

 (1906) and supplement (1918) — the nomenclature now in general 

 use — and this results in abo'ut half of the names used in Eyles' 

 list being discarded, and now regarded as synonyms. In view 

 of this, I have prepared a complete list of the Pteridophyta of 

 S. Rhodesia, using present nomenclature, and showing synonymy 

 as used in my first edition or in Eyles' list. The localities men- 

 tioned in these have not been repeated, nor additional localities 

 given for these species, but localities are given for all additional 

 species. 



It may be necessary tO' further investigate Aspleniion liollandii, 

 Sim, which corresponds exactly with specimens from Kilimandjaro 

 sent by Prince Bonaparte to' me, named Aspleniuni. hypomeJas, 

 Kuhn. Kvdm (" Filices Africanae," page 104, 1868) gives no 

 description, but cities as synonyms " DavaUia >iigresccns, 

 Hk. ic. f. Gent. II., tab. 93 — LoxoscapJic nigicscenfs, INIoore, 

 Index, 297," from Fernando Po (]\Iann 448, in distr. hb. 

 Ivew, 253. C. Christenson maintains the species as A. liyponiclas, 

 Kuhn, and with the above synonyms, as from Fernando Po' only. 

 If the species belongs to continental Africa as well as to 

 Fernando Po, my name may be a synonym, or the fern may be 

 specifically distinct; this has to' be investigated.
